Hi folks,

(sorry for starting a new thread, I lost my old email so I had to start fresh 
this week)

I just posted a new F11 wallpaper mockup: 
https://fedoraproject.org/w/uploads/0/0d/Artwork_F11_greek-concept_mockup2_mo.png


On the plymouth front, I am likely to be a bit busier at work this release than 
the F10 one, so I would really appreciate some of ideas as to what people would 
like during the system boot. The possibilities are pretty much limitless but it 
would be a good thing to conserve the CPU and keep the number and size of images 
included in the initrd to a minimum. Take a look at some examples from last year 
[1-3]. Moving images around like in [1] is trivial, while things like the solar 
flares in [2] and [3] are a lot harder so I won't be able to create too many 
mockups of these.

FLOSS Multimedia Support in Fedora

2009-02-08 Thread Martin Sourada
Hi,

sorry for cross-posting but I wanted all interested parties to not miss
this email ;-)

There has been some media related discussion in the -devel list and one
of the points I have taken form it is that we should promote FLOSS
multimedia and don't blame others for doing it (even if it's done in a
not ideal way)... Now, the problem is that the actual support of these
in our system is crappy. Out of the combinations of two FLOSS containers
(matroska and ogg) and two FLOSS video codecs (dirac and theora) I know
only one (ogg + theora) actually works in xine-lib (used by KDE4) which
is pathetic.

So I created a wiki page (not sure what name space to use, so I put it
under my user page for starters) [1] which tracks the situation. I don't
have much time lately due to university duties, so I put there only
things I know of and didn't researched further. So if you know of any
FLOSS container, video or audio codec, feel free to add it there. Also
feel free to reference upstream bugs about the mentioned issues. The
videos used for reference testing are available at my fedora people page
[2].

Thanks,
Martin

Re: Fedora Bangladesh Logo

 Ups, my bad, I should have not let such a large attachment in, my bad...

 Angel, when you send such a logo for preview, you can safely use a smaller
 resolution, not a huge image. You can also send a vector version.

 Other than that, no much to talk about it, it is just the the Fedora logo
 with the word bangladesh below it... I think I would try to use another
 shade of blue, one of the two blues used in the logo, maybe make the width
 of the bangladesh word the same as the width of the bubble and increase
 the thickness of the font by adding  a stroke in the same blue color as the
 text body.

Hi,
I apologies for sending such a large attachment.

Now it will be very helpful if you can please help me create the logo, the
way you explained it. I hope you have already understood, I am not good at
art.
Thank you.

I don't think that is the correct take-away.  Everything works in gstreamer.

The correct conclusion is that support for free formats in media
infrastructure primarily designed, built, and maintained for non-free
formats currently stinks for the free stuff.

It's another indicator that Fedora should discontinue shipping these
non-free media focused infrastructures rather than continuing to patch
the non-free stuff out.

Of course, support for the free formats should be fixed in that, but
that really shouldn't be a Fedora issue.

 [2].

It's probably important to have a more complete test.

Right now you're using what is probably the simplest possible test:
Just a regular file with video in it. That case is important, but it
is also important to test more complicated cases, such as tests
including audio, subtitles, oddball muxing, and chaining.   It's no
good if a player works for your simple case but crashes as soon as
someone gives it a subtitled input.

It would also be good to try all mixtures of (FLAC|Speex|Vorbis) *
(Theora|Dirac) * (w/ | w/o subtitles) * (OGG|Mkv) which is 24
combinations by itself.
(although I don't know how worthwhile the Mkv testing is— as far as I
can tell it's mostly unseen outside of the movie piracy / anime fansub
sites; and at those its usually used with H264)

For Ogg it's also important to test seeking, because some applications
have historically gotten it wrong. Seeking with Ogg should be done
with Newton–Raphson (ideally) or bisection. There have been broken
applications (ffmpeg in the past; for example) which seek in Ogg with
a linear scan starting at the file beginning, which is quite
intolerable for any reasonably large file.  Unfortunately this test
needs a large (~hundreds of MBytes) test file, so it's hard to
distribute a test.


Some of the proprietary-codecs focused tools provide their own home
grown implementations of the codecs (i.e. ffmpeg). These often do not
implement the full spec, so its important to test their behaviour.

Here are some resources for doing that:

Some good tests for Ogg/Theora:

There are test vectors for Vorbis here:
